Radeon R9 M365X 72000 MB/sec
Radeon HD 3850 256MB 52992 MB/sec
Difference: 19008 (36%)

Texel Rate

The Radeon R9 M365X will be a lot (approximately 246%) faster with regards to AF than the Radeon HD 3850 256MB. (explain)

Radeon R9 M365X 37000 Mtexels/sec
Radeon HD 3850 256MB 10688 Mtexels/sec
Difference: 26312 (246%)

Pixel Rate

The Radeon R9 M365X will be a lot (more or less 38%) better at anti-aliasing than the Radeon HD 3850 256MB, and also should be capable of handling higher resolutions without slowing down too much. (explain)

Radeon R9 M365X 14800 Mpixels/sec
Radeon HD 3850 256MB 10688 Mpixels/sec
Difference: 4112 (38%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Bandwidth is the maximum amount of information (counted in megabytes per second) that can be transferred over the external memory interface in one second. It's worked out by multiplying the interface width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
